Patent GB-2070879-A (GB)
Title: Range finding apparatus
IPC: G01S11/12
Filed: 1980-03-04
Abstract: Known range finding techniques using binocular vision are useful only in circumstances where the existance and position of an object whose range is to be determined is already known. This limitation is eliminated by the illustrated apparatus which receives infra-red or visible radiation through two apertures 2 and 3 and focusses the two respective fields of view at a common image plane 15. A photodetector 14 is located at the image plane and the two images are scanned vertically across this photodetector by a drum 11 carrying reflective surfaces 12. Because of the separation of the apertures 2 and 3 a target in the field of view gives rise to two signals from the sensor 14, the time separation between these signals depending on the range. A circuit 18 measures the time separation and actuates an alarm 25 if the range is within predetermined limits and if various other conditions pertain. The casing 19 rotates in azimuth and the azimuth bearing of the detected target is indicated to the operator by an indicator 26. <IMAGE>
Patent GB-2079334-A (GB)
Title: Twisting yarns
IPC: D01H1/11
Filed: 1980-03-20
Abstract: Method for inserting twist in a yarn 10 drawn from feed rollers 16, 16a towards twisting means 18 comprises periodically gripping the yarn eg by means of rollers 22, 22a at a first position between the feed rollers and the twisting means to form a first temporary twist barrier, and periodically gripping the yarn by means of rollers 24, 24a at a second position between the first position and the feed rollers 16, 16a to form a second temporary twist barrier, the periods of gripping at the first and second position being arranged so that one temporary twist barrier is always present at either the first position or at the second position. By this means, a tension in the yarn 10 in the zone between the feed rollers 16, 16a and either the first or second feed rollers is controlled and may be held less than the tension in the yarn upstream of the first feed rollers 20, 22a, so as to reduce yarn breakage as the yarn leaves rollers 16, 16a. <IMAGE>

Title: Method and apparatus for packing a resilient body in compression and the body so packed
IPC: B65B63/02
Filed: 1980-07-29
Abstract: Apparatus for packaging a compressible body e.g. a sponge into a tube has a surface (20) which receives the sponge between a fixed jaw (21) and an opposed movable jaw (23), the jaws having concave surfaces, which when the jaws abut, define a cavity for the compressed sponge. A platen 32 overlies the jaws (21, 23) and moves normal to the surface (20) between an open position, at which the sponge is positioned on the surface (20), and a closed position, in contact with the jaws, at which the sponge is flattened prior to being compressed further upon movement of the jaw (23) towards the fixed jaw (21). A tube is supported in a receiving position axially aligned with one end of the cavity and a plunger (31) aligned with the other end of the cavity ejects the compressed sponge from the cavity into the tube. Control means is connected to pneumatic actuators to operate them in sequence to move the platen (32) to the closed position, close the jaws (21, 23) and then eject the compressed sponge into the tube. The cross-sectional area of the sponge in its uncompressed state is 5 to 12, preferably 6 to 8, times that of the tube. <IMAGE>

Title: Gas turbine engine test bed with exhaust heat recovery
IPC: F02C7/08
Filed: 1980-11-20
Abstract: As a fuel-saving measure, a test bed (1) for gas turbine engines, particularly jet propulsion engines, is provided with a heat exchange system which exchanges heat between the exhaust efflux (B,C) of the engine (9) being tested and the test bed intake air (A), so as to produce warmer engine intake air (A min ). To take account of variable atmospheric temperatures and differing engine powers, the amount of heat discharged by the intake air heat exchanger (19) to the intake air can be varied by varying the mass flow rate of circulation of heat exchange medium around the system and changing the effective heat exchange area of the heat exchanger (17) which collects heat from the exhaust efflux. <IMAGE>

Title: Piles
Inventor: FLEMING WILFRED GEORGE KENNETH
IPC: E02D5/38
Filed: 1982-01-22
Abstract: The method involves driving into the ground a mandrel (1) carrying a pile shoe (2) and pumping a cementitious mixture (4) into the hole through the interior of the mandrel (1) as it is being driven into the ground. The cementitious mixture (4) leaves the interior of the mandrel (1) and enters the annular gap between the mandrel (1) and the earth surface via one or more holes (34) located at or close to its lower end and generally just above the pile shoe (2). The mixture (4) is maintained at a positive pressure relative to its surroundings, and is allowed to set after the mandrel (1) has reached the desired depth and has been withdrawn leaving the shoe (2) behind. The driving rig need not have the bulk required to exert the massive pulling forces required in conventional piling systems where a temporary casing which has been driven tightly into the soil is withdrawn prior to completion of the pile.
